Hi there, my baby cockatiel did something strange today, she kept dunking her beak into the fresh water i put in, (i do this twice a day) then it looks like she snorting into the water. I saw what looked like a bit of dust. She did it a couple of times and then rubbed her beak and for the rest she's been acting normal but before she did that it seemed like her nostrils looked slightly red. If someone could just indicate if this is normal or am I just being paranoid.
